Baseball America on Joe Serafin and Miguel Gonzalez

Jeff (England): Joe Serafin has made a great start to his pro career, especially for a 37th rounder, with a 4.14 K/BB, 1.67 BB/9 as well as an improving K/9 since his jump to Low-A, but is he is for real? And do you know much about what he throws?

Matthew Eddy: White Sox lefty Joey Serafin works in the mid-80s with a fringy breaking ball, but the University of Vermont product shows poise and command, which often can be enough to dominate in Rookie ball and low Class A.

and from a question on Appalachian League prospects:

The White Sox have an 18-year-old Venezuelan catcher named Miguel Gonzalez with Bristol. He’s got a bit of a thick body but he impressed observers by hitting .300 and by driving the ball consistently (15 doubles). If he can stay at catcher, he’s got a shot.
